For the last two or three days, when I click on a thread (especially longer ones methinks) I get an "operation aborted" message about 50% of the times I try. I have to double-click the back button and try again, and sometimes it takes four or five goes to get into the thread. I have also found that having a Mudcat window open often prevents me from opening another (new) window - I have to close Mudcat (which always results in a "window busy" message) before I can open another window. I'm Vista and I use IE8. Cheers for any sympathy or advice!
